Karazin popup.description2 Subject of research - nano- and microcrystalline powders. The purpose of work - development of technology of obtaining of composite ceramics components. Synthesis of the initial powder hydroxyapatite, carbonated hydroxyapatite, tricalcium phosphate. Synthesis of magnetic filler such as magnetite, maggemite and calcium hexaferrite in the form of nano- and microcrystals. Methods of research - x-ray phase analysis, scanning and transmission electron microscopy, infra-red spectroscopy, low- and high-temperature derivatographic analysis, complexonometry titration of inorganic ions. Based on the improvement of existing and newly developed technologies the calcium phosphate fine-grained powders (hydroxyapatite, carbonated hydroxyapatite and biphasic system hydroxyapatite/?-tricalcium phosphate, where the content of tricalcium phosphate can vary from zero to one hundred percent) and magnetic powders (magnetite, maggemite and calcium ferrite) had been synthesize. The obtained materials are the base raw materialfor synthesis of composite ceramic implants where functional parameters meet the requirements of hyperthermia treatment of oncological diseases of human bone tissue. Bioactive properties of such ceramics are independent of the magnetic component contents, and magnetic properties can be controlled by means of selection of magnetic components of some or another composition and morphology of particles.
